Chaos erupted at Coney Island Beach on Monday when a group of teenagers got into a violent altercation, leading to the arrest of at least 16 individuals, as reported by both video footage and law enforcement officials.

The fight erupted around 6:30 p.m. on the sand and along the historic Riegelmann Boardwalk near West 15th Street before spreading to surrounding streets, police and sources said.

The pandemonium, which took place as hundreds of teens converged on the popular summer destination amid record-breaking heat in the Big Apple, prompted a massive mobilization of police officers.

It’s unclear what sparked the brawl, and there were no immediate reports of injuries.

Footage shows multiple teens in handcuffs being led away by NYPD cops as a sea of teens congregate on the sand.

It’s unclear if the teens seen being arrested in the video were involved in the fight.

At least three dozen officers created a human barricade as cops tried to restore order to the chaotic scene. 

Several chases broke out, and a female paramedic was crashed into as a scrum of cops sprinted after a suspect, the video shows.

Officers caught up with the suspect and slammed him to the ground next to a row of park benches and flowering bushes, according to the footage.

The teen chaos spread across the boardwalk to Brighton Beach, almost a mile to the east, as the mercury topped out in the 90s across the city.

One young man was chased down by officers to an area underneath the boardwalk and tackled, according to another video obtained by The Post.

It appeared the teenager was complying as four officers were crouching on top of him when suddenly one of the cops tasered the suspect on his calves and the back of his knees. 

A teen in the crowd shouted: “What are you doing?” as the suspect thrashed in the sand.

Police had no comment about the use of a Taser on the teen in Brighton Beach.

Charges are pending in all of the arrests, and the incident remains under investigation.

Earlier this month, several fights broke out during a high school senior skip day party at Jones Beach State Park, forcing police to disperse the group with a helicopter and temporarily shutting down the beach.

A large group of youths from several high schools in Nassau County and Queens gathered on the Wantagh, Long Island, waterfront when some of them started throwing punches, with several fights starting in different pockets of the group of high schoolers.
